Title: Quantization feedback circuit
Inventor: KOBAYASHI NOBUYOSHI
IPC: G11B5/09
Filed: 1994-08-30
Abstract: PURPOSE: To obtain a quantization feedback circuit capable of well reproducing the low frequency range components of ternary analog signals in which the low frequency range components are lost. CONSTITUTION: The RR-I equalization signal from an equalizer 12 is supplied as a ternary equalization signal to comparators 19, 20 constituting a ternary level identifying means via an analog adder 18. The output of this comparator 19 attains a '1' when the ternary equalization signal is higher than the threshold voltage + Eth. The output attains a '0' in other cases. On the other hand, the output of the comparator 20 attains a '1' when the ternary equalization signal is lower than the threshold voltage - Eth and the output attains a '0' in other cases. The output signal of these comparators 19, 20 are ORed and are led out as reproducing data to an output terminal 24. The outputs of the compartors 19, 20 are supplied to a differential amplifier 2 as a ternary analog signal restoring means.  The low frequency components are extracted by a low-pass filter 23 by the restored ternary analog signals and the ternary equalization signal is formed by adding these components to the output of the equalizer 12 by an adder 18.

Title: Water distributing system in building water supply system
Inventor: SENOO YASUTOSHI
IPC: C02F1/20
Filed: 1992-07-08
Abstract: PURPOSE:To reduce the volume of a deaerator by a method wherein raw water is deaerated, and stored in a deaerated water tank, water is conveyed to an elevated water tank by a lift pump while the deaerated water tank is supplied with deaerated water and water is stored at all times. CONSTITUTION:When load 2 is supplied with water and the water level regulator 17 of an elevated water tank 3 is operated at a specified water level, a lift pump 7 is turned on and the water tank 3 is replenished with deaerated water from a deaerated water tank 5. When the water level of the water tank 5 is lowered and the water level regulator 17 is operated, a deaerator 8 is driven, and deaerated water is fed up to the specified water level of the water tank 5. When raw water in a water receiving tank 10 is also lowered up to a predetermined water level, a solenoid valve 21 is opened, and raw water is received. When load 2 temporarily increases and the supply of the water tank 3 with deaerated water reaches the capacity or more of the device 8 and the water level of the water tank 5 is lowered up the lower limit of a low-level detecting sensor 13, a solenoid valve 16 is opened, and water is supplied urgently up to the water level regulator 17 through a bypass circuit 12 from the tank 10. Accordingly, a deaerator having small capacity corresponding to mean water usage can correspond to the water level, thus largely reducing the cost of equipment.
